Maybe I have to look in the options to disable this, but cruise control annoyingly reduces or accelerates based on the speed signs irrespective of what I set my cruise to. I am cruising with traffic at 75 and car suddenly slows to 55 as it reads a speed sign. I have to then increase the cruise speed to catch up with traffic. Surprisingly I am cruising on a 55 mph road and it read the 70mph speed limit sign on the free way next to me and started accelerating to 70. I am not sure why this is a standard setting, seems like a safety issue. I have to find the option to disable this.
